Things have improved somewhat. I upgraded to BIOS A05 for my machine and that helped a bit, but I still get the problem about once per song in xmms and I can even trigger it with a little script: while cat /proc/apm; do echo ''; done (I saw the previous posts that seemed to suggest this was a bad interaction with apm.) It doesn't happen on every read from /proc/apm. Some cause a slight skip in xmms, some cause no skip at all, and some make the entire remainder of the song go staticky. I could understand either of the first two problems but I don't understand what would mess things up far past the time of the disruption. What else can I do to track down the problem? I'm fine with C and I'm not a complete stranger to the kernel but I've never written or worked on a device driver. -- >>>-- Nathaniel Gray -- Caltech Computer Science ------> >>>-- Mojave Project -- http://mojave.cs.caltech.edu --> ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf
